Composite films were prepared by combining different concentrations of curcumin with chitin and glucan complexes (CGCs) extracted from Agaricus bisporus via a solution casting method. The developed curcumin doped CGC (CGC/Cu) films were characterized in terms of surface, optical, structural, barrier, mechanical, antioxidant, and antimicrobial properties. The biodegradability of CGC/Cu films was determined in soil for 14 days. The incorporation of curcumin significantly affected the surface morphology and improved light barrier properties, radical scavenging activity, and total phenolic content of the films. The CGC/Cu films containing different concentrations of curcumin showed antibacterial activity against Escherichia coli, while antibacterial activity against Staphylococcus aureus was not observed with the developed films. Afterward, the microbial properties of the fresh chicken breast were examined during refrigerated storage for 10 days. The shelf-life of chicken samples wrapped in the developed film was extended at least 40 % compared to the control sample. In conclusion, curcumin incorporated CGC based films can serve as a promising biodegradable active packaging material to improve the shelf-life of meat products.
复合膜是通过溶液浇铸法将不同浓度的姜黄素与从双孢蘑菇中提取的壳聚糖和葡聚糖复合物(CGC)结合制备而成。所开发的姜黄素掺杂 CGC(CGC/Cu)薄膜在表面、光学、结构、阻隔、机械、抗氧化和抗菌性能方面进行了表征。在土壤中对 CGC/Cu 薄膜的生物降解性进行了为期 14 天的测定。姜黄素的掺入显著影响了薄膜的表面形态,提高了光阻隔性能、自由基清除活性和总酚含量。含有不同浓度姜黄素的 CGC/Cu 薄膜对大肠杆菌表现出抗菌活性,而对开发的薄膜则没有观察到金黄色葡萄球菌的抗菌活性。随后,在冷藏储存 10 天期间检查了新鲜鸡胸肉的微生物特性。与对照样品相比,用开发的薄膜包装的鸡肉样品的保质期至少延长了 40%。总之,掺入姜黄素的 CGC 基薄膜可用作有前途的可生物降解的活性包装材料,以延长肉类产品的保质期。
